Many unknown WPS status queries are logged periodically
Description
Using GeoServer with GEOTOOLS_DEVELOPER_LOGGING level, will result in many logged queries for unknown processes.
I'm using GeoServer with the WPS plugin and the process status on the database.
Even with an empty database and no running processes, I find the following queries every 3 seconds.
